LH2.2 intermitant fail, maybe tps related?
1982 US 928S 5 spd, Euro hybrid motor, US 85 wiring harness, LH, and EZK brains. Some issues with the throttle position switch last week, but running fine since then until today during dyno runs the fuel injection seemed to just cut out completely. releasing the accelerator seemed to reset the problem, but despite a fair amount of looking no problems found.
Fuel pressure 50+., relays all checked out, battery connections cleaned, throttle switch replaced, wires wiggled. Nothing seemed to fix it except unplugging the throttle position switch.
I'm not "sure" its exactly in sequence, but we took a break from the fuel injection issues and replaced all the bad light bulbs around the car including a new relay for headlights (raised up, didn't turn on before relay).
Now we can't seem to make the fuel injection glitch reappear.
Monday the testing continues, any thoughts?
